BUTTON-SETTING INSTRUM ENT.

SPECIFICATION forming part of Letters Patent No. 336,859, dated February 23, 1886.

Application filed April 23, 1885.

To all whom it may concern.-

Be it known that I, THOMAS E. KEAVY, a citizen of the United States, and a resident of Kent, in the county of Portage and State of Ohio, have invented a new and useful Improvement in Setting-Instruments for Button- Fasteners, of which the following is a specification.

My invention has relation to improvements in that class of setting-instruments for buttonfasteners in which the fastener consists of a single prong provided with a head,the pointed end of which is forced through the material to which the button is to be attached and turned through the eye of the button.

The object of my invention is to provide devices to hold the fastener rigidly in position at the moment it is first thrust forward, to insure its accurate entrance into the turning device after passing through the material, and to release it as the head is forced against the fabric.

My invention consists in the devices illustrated in the accompanying drawings, as hereinafter explained, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation; Fig. 2, a front elevation; Fig. 3, a plan; Fig. 4, a vertical central section at the line so a: of Fig. 3, and Fig- 5 a similar view with collar pressed down and jaws open.

The entire machine embodies a turning device, A, and a fastener-holder, B; but as the latter is the only subject of this application the shape and construction of the former is of no significance.

The two parts may be attached to the jaws of a hand-tool, as shown in Fig. 1, or any other arrangement may be adopted, the essential requisite being that the fastener be held in the holder B and by it pressed into the turning device A.

In the accompanying drawings, O is a cylindrical post, the top of which is countersunk to form a rest for the head of the fastener. Upon this post is a sleeve, D, having on the front and back two parallel plates, d d, and connected with and projecting above the plate d a stud, c. This sleeve, which slides freely on the post O, is held up by a spring, E, and prevented from turning, and its travel limited by a screw, 0, resting on a plane face on the front of the post.

Serial No. 163,1l3. (No model.)

Between the ends of the plates d d are hinged two jaws, F F, which meet above the end of the post 0, and are held together by springs G G. In the face of each jaw is a notch,which notches register above the center of the post 0 and constitute a clamp for the fastener.

In operation the head of the fastener I, Fig. 4, is placed in the hollow end of the post with the body clamped in the notches of the jaws F F, the material to which the button is to be attached being interposed between the point of the fastener and the turning device. The tool is then pressed through the material toward the turning device,which the fastener enters accurately, being held rigidly in the holder. After it has passed into the proper opening of the turning device through the material to which the button is to be attached, the stud c encounters the turning device A and arrests the further advance of the sleeve D. The post 0 continues to advance through the sleeve D, and encountering the inner faces of the jaws F F separates them, and presses the head of the fastener against the material.

I claim- 1. In a button-fastener setting-instrument having a fastener-holder and fastener-upsetting devices adapted to act in conjunction with each other, a fastener-holder consisting of a rigid post, a sleeve mounted and sliding thereon, held upward by a spring, fastenerclamping and holding jaws pivoted or hinged to said sliding sleeve on opposite sides thereof, and springs acting on said jaws to hold them together above the end of the post, said jaws being separated and swung outward by coming in contact with the end of the post as the sleeve slides thereon, substantially as described.

2. The herein-described fastener-holder, consisting of the post 0, sleeve D, spring E,

jaws F F, springs G G, and stud c, all constructed and arranged substantially as shown, and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of March, A. D. 1885.

THOMAS E. KEAVY.
